Soy lecithin supply, about the stability and storage conditions of soy lecithin
The biggest use of soybean incubation phospholipids is as food additives, and the basic use is as feed additives. It is also used in medicine, cosmetics, leather, asphalt emulsifier, etc.
Soy lecithin is an extracted substance from soybeans. It is also one of the lipid components needed by the human body and is used in industry mainly as an emulsifier, moisturizer and thickener. It is also used as a nutritional supplement.
About the stability and storage conditions of soy lecithin.
The physical state of lecithin varies from a viscous semi-solid to a powder state, depending mainly on the content of free fatty acids.
The color ranges from brown to bright yellow, depending on whether it has been bleached and the degree of purification.
It oxidizes, discolors and degrades when exposed to heat; degrades at 160-180°C for 24 hours; degrades at extreme pH values and is both hygroscopic and microbially degradable.
Lecithin in liquid or wax form degrades at room temperature or above, and causes separation below 10°C.
Store in airtight containers, protected from light and oxygen; purified lecithin should be stored in airtight containers below freezing point.
Soluble in aliphatic hydrocarbons, aromatic hydrocarbons, halogenated hydrocarbons, mineral oils and fatty acids, insoluble in cold vegetable oils, animal oils, polar solvents and water.
